- IMPROVEMENT IN STEAM SUPERHEATERS.

Speciication forming part of Letters Patent No. 123,542, dated February 6, 1872.

To all whom it may concer-n:

Be it known that l, HENRY Yos'r, ot Columbia, in the county of Lancaster' and State of Pennsylvania, have invented a new and Improved Combination in Steain-Genentors, of which the following is a description, reference being had to the accompanying drawing nraliing part of this specilication.

Figure l is a vertical section. Fig. 2 is a cross-section, above the continuous pipe, on an enlarged scale 5 Fig. 3, a portion of the continuous steam-pipe, joined alternately.

Fig. 1 represents vthe vert-ical boiler, which consists of the ash-box A; the tire-box and grate F; the Water-space B, sho\vn to extend around the tire-pot or furnace F to the grate. An injector' of the ordinary kind in use can be attached at K. Above the tire-box the Waterspace is widened, say, from three to six inches. lhere is a centra open space, say, eighteen inches, which I will call the caloriccha-uiber F. This is open from the tire-pot F to the tlue C that leads to the smoke-stack. This annular Water-case or boiler B may be made in a single section, and connected to the dome and furnace in the ordinary manner. The steam generated passes out through the top into a pipe, which is carried to the outside of the boiler and provided with a valve, D, and with a short turn entered back to connect with a vertical pipe marked 1, Fig. 2.

The steam passes down within the caloric chamber, and belenY connects with No. 2, passes up 2 and down 3, and so on, coming up 12; it crosses to an inner series, 13, down and up 14, thus passing' up and down this connected series ot' pipes, subjected to the heat Within the caloric-chamber F, therebgv becoming superheated, and may be conveyed at this high tem pera-ture, say, 3150 Fahrenheit, to the steamchest, 1n like manner as ordinary steam is Worked, but with a much-increased power'or expansion.

For producing a still greater heat, and generating dr)Y hot air, to be applied to hea-ting purposes, l connect a small furnace, G, Fic'. 1, in such a manner that the lower end ot' the continuous pipe is brought outside, and provided with a valve, E. This pipe is turned do \\'n an d outward within the furnace Gr, above the ignited fuel in the furnace, into which it blows, expands, and escapes through an opposite enlarged pipe, H, to be carried to any desired point for heating dwellings or kitchenranges, or purposes to which the superheated steam can be applied.

It is believed that by this combination a valuable generator', on a small scale, will be sufficient to propel sewing-machines or for driving one or two horse-power engines for farm or shop Work. The fuel or heat that generates the steam is utilized to superheat the saine, and thereby perform its Work more highly expanded.

I do not claim a vert-ical boiler with an inner tlue open to the tire-pot; nor do'I claiin a coil or continuous steam-pipe for superheating steam, separately considered, as such have been used before.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. I claim the furnace G, With its Outlet H, opposite a steam-jet nozzle, substantially as and for the purpose set forth.

2. In combination with my furnace Gr, I claim the use of a portable steamgenerator, substantially made in the manner shown, and for the purpose specified.
